Mitigating inter-symbol interference (ISI) in impulse radio is one of the challenges in achieving the high data rate potential of Ultra Wideband (UWB). Available techniques such as the use of Multiband OFDM and equalizer provide a good solution but they require complex implementation. This letter investigates and expands a newly proposed ISI reduction technique proposed in [1] named "shift window" approach. The shift window approach was not designed to combat ISI under a severe indoor wireless channel. An enhancement based on the generalization of the shift window approach is introduced for ISI reduction for wireless personal area network (WPAN). The newly proposed approach is shown to perform better under severe ISI.
